A balance of engineering and design

In the world of consumer products, it often seems like engineers are making things for other engineers while designers are making things for other designers. That leaves a lot of products either too complicated or too precious to be useful. In fact, it’s rare to find a product that balances the two sometimes competing, sometimes complementary, elements. When Airmega’s creators began to conceive of an air purifier to lead the market, they knew the design had to be a driver on equal footing with the engineering.

One of the key engineering innovations that makes Airmega a leading air purification provider is the presence of not one, but two, activated carbon HEPA filters. You may have heard of activated carbon, also known as activated charcoal, before. It is a filtration technology used in an array of everyday products. This presence of two filters essentially doubles the amount of air processed through the walls and out the top of the unit.

Often, this type of engineering robustness will come at the expense of design aesthetics but Airmega’s creators were able to build the double intake configuration into a design that fits into the home environment. Of note, the distinctive hole pattern on the unit’s outer surfaces were repeatedly tested to optimize air intake.

Among those to have taken notice is none other than Wired magazine, when Airmega appeared in their Daily Fetish section. The title says it all: “This Air Purifier Has Brains and Doesn’t Look Like Garbage.” Similarly, Gadget Review named Airmega the “Best HEPA Air Purifier of 2017.” They raved about Airmega’s double-filter engineering while also stating, “Aesthetically, this machine rocks the boat. Its unique design is visually appealing in any space.” What’s more, according to tech blog ChipChick, setup is easy, in part because the unit works directly with Wi-Fi networks, rather than through Bluetooth.

Balance: You know it when you see it, feel it, use it.


1Coway air purifiers has been proven to trap dust, pollen, dander, viruses and bacteria in the air based on KCL (Korea Conformity Laboratories) testing.They have been tested in a 30㎥ size chamber according to the Korea Air Cleaning Association standard (SPS-KACA 002-132:2022 Modified) to measure the 0.01㎛ size of particle removal rate. It was tested on maximum airflow speed in normal room temperature and humidity conditions. The performance may vary in the actual living environment of customers.
→ Tested with Airmega Aim, 150, 160, AP-1216L, AP-1512HH, AP-1512HHS, 200M, Icon, IconS, 230, 240, 250, 250 Art, 250S, 300, 300S, 400, 400S, ProX

299.97% of viruses, bacteria, fungi and pollen were verified to be removed from the air for Coway air purifiers which have Green True HEPA™ filter applied based on the Japan Food Research Laboratories(JFRL) testing according to JEM 1467 standard.

3Aerosol test conducted in a Biosafety level 3 laboratory with two Coway air purifier models, Coway Airmega 250 and 400 for removal of SARS-CoV-2 Aerosol by US based MRI Global, a not-for-profit laboratory and partner of US Department of Defense. The test was conducted in a 13.1ft3 chamber. Virus was aerosolized for 15 minutes and the product was turned on high for 2 minutes. Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19. Coway Airmega 250S and 400S are identical to the tested models and has equal performance with an additional mobile connectivity function.

4The concentration of ammonia, acetaldehyde and acetic acid were proven to be removed within 30 minutes by FCG Research Institute, Inc. Human Life Science Lab. It is not a demonstration result in the actual use space. Not all odors and gases may be supported. → Tested with Coway Airmega 150, 160, AP-1512HH, AP-1512HHS, 400, 400S

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
